23 Chapter 2 Safeguarding Your Network For a wireless connection, the SSID, also called the wireless network name, and the wireless security setting must be the same for the wireless router and wireless computers or wireless adapters. NETGEAR strongly recommends that you use wireless security. Warning: Computers can connect wirelessly at a range of several hundred feet. This can allow others outside of your immediate area to access your network. This chapter includes: Planning Your Wireless Network Manually Configuring Your Wireless Settings on page 2-4 Using Push 'N' Connect (WPS) to Configure Your Wireless Network on page 2-10 Connecting Additional Wireless Client Devices After WPS Setup on page 2-14 Restricting Access to Your Router on page 2-16 Planning Your Wireless Network For compliance and compatibility between similar products in your area, the operating channel and region must be set correctly. To configure the wireless network, you can either specify the wireless settings, or you can use Wi- Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security. To manually configure the wireless settings, you must know the following: SSID. The default SSID for the wireless router is NETGEAR. The wireless mode (802.11g, or b) that each wireless adapter supports. Wireless security option. To successfully implement wireless security, check each wireless adapter to determine which wireless security option it supports. See Manually Configuring Your Wireless Settings on page

24 Push 'N' Connect (WPS) automatically implements wireless security on the wireless router while, at the same time, allowing you to automatically implement wireless security on any WPS-enabled devices (such as wireless computers and wireless adapter cards). You activate WPS by pressing a WPS button on the wireless router, clicking an onscreen WPS button, or entering a PIN number. This generates a new SSID and implements WPA/WPA2 security. Note: NETGEAR s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see All other Wi- Fi-certified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect. To set up your wireless network using the WPS feature: Use the WPS button on the side of the wireless router (there is also an onscreen WPS button), or enter the PIN of the wireless device. Make sure that all wireless computers and wireless adapters on the network are Wi-Fi certified and WPA or WPA 2 capable, and that they support WPS configuration. See Using Push 'N' Connect (WPS) to Configure Your Wireless Network on page Wireless Placement and Range Guidelines The range of your wireless connection can vary significantly based on the physical placement of the wireless router. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices. For best results, place your wireless router according to the following guidelines: Near the center of the area in which your PCs will operate. In an elevated location such as a high shelf where the wirelessly connected PCs have line-ofsight access (even if through walls). Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless phones. Away from large metal surfaces. Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna in a horizontal position to provide the best up-and-down coverage. If using multiple access points, it is better if adjacent access points use different radio frequency channels to reduce interference. The recommended channel spacing between adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11). 2-2 Safeguarding Your Network

25 The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer. Wireless Security Options Indoors, computers can connect over g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside your immediate area to access your network. Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WNDR3300 router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs. There are several ways you can enhance the security of your wireless network: Wireless data security options Range: up to 300 foot radius Figure 2-1 1) Open system: easy but no security. 2) WEP: security, but some performance impact. 3) WPA-PSK: strong security. 4) WPA2-PSK: very strong security. WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK. WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared key to perform authentication and generate the initial data encryption keys. The very strong authentication along with dynamic per frame re-keying of WPA makes it virtually impossible to compromise. For more information about wireless technology, see the link to the online document in Wireless Networking Basics in Appendix B. Safeguarding Your Network 2-3

26 Manually Configuring Your Wireless Settings You can view or manually configure the wireless settings for the wireless router in the Wireless Settings screen. If you want to make changes, make sure to note the current settings first. Note: If you use a wireless computer to change the wireless network name (SSID) or wireless security settings, you will be disconnected when you click Apply. To avoid this problem, use a computer with a wired connection to access the wireless router. To view or manually configure the wireless settings: 1. Log in to the wireless router at its default LAN address of with its default user name of admin, and default password of password, or using whatever user name, password, and LAN address you have chosen for the wireless router. 2. Select Wireless Settings from the main menu to display the Wireless Settings screen: Figure 2-2 The settings for this screen are explained in Table 2-1 on page Select the region in which the wireless router will operate. 4. For initial configuration and test, leave the other settings unchanged. 5. To save your changes, click Apply. 2-4 Safeguarding Your Network

27 6. Configure and test your computers for wireless connectivity. Program the wireless adapter of your computers to have the same SSID and wireless security settings as your wireless router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the wireless router. If there is interference, adjust the channel. Table 2-1. Wireless Settings Settings Name (11N SSID) Name (11G SSID) Region Mode 11 N Channel 11 G Channel Description This is the wireless network name. Enter a 32-character (maximum) name in this field. This field is case-sensitive. In a setting where there is more than one wireless network, different wireless network names provide a means for separating the traffic. Any device that you want to participate in a wireless network must use the SSID. The location where the router is used. Specify which data communications protocol is used. You can select one of the following modes: Up to 270 Mbps at 2.4 GHz. Performance mode, using channel expansion to achieve the 270 Mbps data rate. The WNDR3300 router uses the channel you selected as the primary channel and expands to the secondary channel (primary channel +4 or 4) to achieve a 40 MHz frame-by-frame bandwidth. The WNDR3300 router detects channel usage and disables frame-by-frame expansion if the expansion would result in interference with the data transmission of other access points or clients. Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz. This is the default mode. Up to 130 Mbps at 2.4 GHz. Neighbor friendly mode, for reduced interference with neighboring wireless networks. Provides two transmission streams with different data on the same channel at the same time, but also allows b and g wireless devices. Up to 130 Mbps at 5 GHz and 54 Mbps at 2.4 GHz. Legacy mode, for compatibility with the slower b and g wireless devices. The wireless channel fields determine the operating frequency used for the 11N or 11G wireless networks. Do not change the wireless channel unless you experience interference (shown by lost connections or slow data transfers). If this happens, you might need to experiment with different channels to see which is the best. Safeguarding Your Network 2-5

28 Table 2-1. Wireless Settings (continued) Settings Security Options Description None. You can use this setting to establish wireless connectivity before implementing wireless security.

32 Using Push 'N' Connect (WPS) to Configure Your Wireless Network If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure the wireless router s SSID and security settings and, at the same time, connect the wireless client securely and easily to the wireless router. Look for the symbol on your client device (computers that will connect wirelessly to the wireless router are clients). WPS automatically configures the network name (SSID) and wireless security settings for the wireless router (if the wireless router is in its default state) and broadcasts these settings to the wireless client. Note: NETGEAR s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see All other Wi-Ficertified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect. Some considerations regarding WPS are: WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not supported by WPS. If your wireless network will include a combination of WPS capable devices and non-wps capable devices, NETGEAR suggests that you set up your wireless network and security settings manually first, and use WPS only for adding additional WPS capable devices. See Adding Both WPS and Non-WPS Clients on page A WPS client can be added using the Push Button method or the PIN method. Using the Push Button. This is the preferred method.

61 Managing the Configuration File The configuration settings of the WNDR3300 router are stored within the router in a configuration file. You can back up (save) this file to your computer, restore it, or reset it to the factory default settings. From the main menu, under Maintenance, select Backup Settings. Figure 4-8 The following sections describe the available options. Backing Up and Restoring the Configuration The Restore and Backup options in the Backup Settings screen let you save and retrieve a file containing your router s configuration settings. To save your settings, click Back Up. Your browser extracts the configuration file from the router and prompts you for a location on your computer to store the file. You can give the file a meaningful name at this time, such as comcast.cfg. Tip: Before saving your configuration file, change the administrator password to the default, password. Then change it again after you have saved the configuration file. If you forget the password, you will need to reset the configuration to factory defaults. Using Network Monitoring Tools 4-9

62 To restore your settings from a saved configuration file, enter the full path to the file on your computer, or click Browse to browse to the file. When you have located it, click Restore to send the file to the router. The router then reboots automatically. Warning: Do not interrupt the reboot process. Erasing the Configuration Under some circumstances (for example, if you move the router to a different network or if you have forgotten the password), you might want to erase the configuration and restore the factory default settings. After an erase, the router s user name is admin, the password is password, the LAN IP address is (or and its DHCP server is enabled. To erase the configuration, click the Erase button in the Backup Settings screen. To restore the factory default configuration settings when you do not know the login password or IP address, you must use the restore factory settings button on the rear panel of the router (see Restoring the Default Configuration and Password on page 7-12). Enabling Remote Management Access The remote management feature allows you to upgrade or check the status of your WNDR3300 router via the Internet. From the main menu, under Advanced, select Remote Management. Figure Using Network Monitoring Tools

63 Note: Be sure to change the router s default configuration password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both uppercase and lowercase), numbers, and symbols. Your password can be up to 30 characters. To configure your router for remote management: 1. Select the Turn Remote Management On check box. 2. Under Allow Remote Access By, specify what external IP addresses will be allowed to access the router s remote management. Note: For enhanced security, restrict access to as few external IP addresses as practical. To allow access from any IP address on the Internet, select Everyone. To allow access from a range of IP addresses on the Internet, select IP Address Range. Enter a beginning and ending IP address to define the allowed range. To allow access from a single IP address on the Internet, select Only This Computer. Enter the IP address that will be allowed access. 3. Specify the port number for accessing the management interface. Normal Web browser access uses the standard HTTP service port 80. For greater security, enter a custom port number for the remote management Web interface. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP. 4. Click Apply to have your changes take effect. Note: When accessing your router from the Internet, type your router s WAN IP address into your browser s address or location field, followed by a colon (:) and the custom port number.

The router is shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The router s default LAN IP configuration is: LAN IP address: Subnet mask: These addresses are part of the designated private address range for use in private networks and should be suitable for most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in the LAN Setup screen. Customizing Your Network Settings 5-1

66 To configure LAN IP settings, log in to the router, and under the Advanced heading, select LAN Setup. The following screen displays: Figure 5-1 If you make changes you must click Apply in order for the changes to take effect. Note: If you change the LAN IP address of the router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again. The LAN Setup fields are explained in the following table. Table 5-1.

The LAN subnet mask of the wireless router. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or wireless router. RIP Direction RIP (Router Information Protocol) allows a wireless router to exchange routing information with other routers. This setting controls how the wireless router sends and receives RIP packets. Both is the default. Both or Out Only. The wireless router broadcasts its routing table periodically. Both or In Only. The wireless router incorporates the RIP information that it receives. None. The wireless router will not send any RIP packets and will ignore any RIP packets received. RIP Version This controls the format and the broadcasting method of the RIP packets that the wireless router sends. It recognizes both formats when receiving. By default, this is RIP-1. RIP-1 is universally supported. It is adequate for most networks, unless you have an unusual network setup. RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting. Use Router as a DHCP Server Starting IP Address Ending IP Address Address Reservation For more information, see Address Reservation on page 5-4. This check box is usually selected so that the wireless router functions as a Dynamic Host Configuration Protocol (DHCP) server. See Using the Router as a DHCP Server on page 5-4. Specify the start of the range for the pool of IP addresses in the same subnet as the wireless router. Specify the end of the range for the pool of IP addresses in the same subnet as the wireless router. When you specify a reserved IP address for a computer on the LAN, that computer receives the same IP address each time it access the router s DHCP server. Assign reserved IP addresses to servers that require permanent IP settings. Customizing Your Network Settings 5-3

68 Using the Router as a DHCP Server By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router s LAN. The assigned default gateway address is the LAN address of the router. The router assigns IP addresses to the attached computers from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN. For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. Click the link to the online document TCP/IP Networking Basics in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network. Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP address. These addresses should be part of the same IP address subnet as the router s LAN IP address. Using the default addressing scheme, you should define a range between and , although you might wish to save part of the range for devices with fixed addresses. The router delivers the following parameters to any LAN device that requests DHCP: An IP Address from the range you have defined Subnet Mask Gateway IP Address (the router s LAN IP address) Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen; otherwise, the router s LAN IP address) Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings screen) To use another device on your network as the DHCP server, or to manually configure the network settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise, leave it selected. If this service is not selected and no other DHCP server is available on your network, you will need to set your computers IP addresses manually or they will not be able to access the router. Address Reservation When you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the router s DHCP server. Reserved IP addresses should be assigned to computers or servers that require permanent IP settings. To reserve an IP address: 1. Click Add. 5-4 Customizing Your Network Settings

69 2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an IP address from the router s LAN subnet, such as x.) 3. Type the MAC address of the computer or server. Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices screen and paste it here. 4. Click Apply to enter the reserved address into the table. Note: The reserved address is not assigned until the next time the computer contacts the router s DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew. To edit or delete a reserved address entry: 1. Select the radio button next to the reserved address you want to edit or delete. 2. Click Edit or Delete. Using a Dynamic DNS Service If your Internet Service Provider (ISP) gave you a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you do not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial Dynamic DNS service, which allows you to register your domain to their IP address, and forwards traffic directed at your domain to your frequently changing IP address. Note: If your ISP assigns a private WAN IP address (such as x.x or 10.x.x.x), the Dynamic DNS service will not work because private addresses are not routed on the Internet. Your router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org. You must first visit their website at and obtain an account and host name, which you configure in the router. Then, whenever your ISP-assigned IP address changes, Customizing Your Network Settings 5-5

70 your router automatically contacts the Dynamic DNS service provider, logs in to your account, and registers your new IP address. If your host name is hostname, for example, you can reach your router at hostname.dyndns.org. From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS screen. Figure 5-2 To configure Dynamic DNS: 1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. For example, for DynDNS.org, select 2. Select the Use a Dynamic DNS Service check box. 3. Select the name of your Dynamic DNS service provider. 4. Type the host name (or domain name) that your Dynamic DNS service provider gave you. 5. Type the user name for your Dynamic DNS account. This is the name that you use to log in to your account, not your host name. 6. Type the password (or key) for your Dynamic DNS account. 7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use Wildcards check box to activate this feature. For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. 8. Click Apply to save your configuration. 5-6 Customizing Your Network Settings

71 Configuring the WAN Setup Options The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the Maximum Transmit Unit (MTU) size, and enable the wireless router to respond to a ping on the WAN (Internet) port. From the main menu, under Advanced, click WAN Setup to view the WAN Setup screen. Figure 5-3 The WAN Setup fields are described in the following table: Table 5-2. WAN Setup Settings Setting Disable SPI Firewall Default DMZ Server Respond to Ping on Internet WAN Port MTU Size (in bytes) Description The Stateful Packet Inspection (SPI) firewall protects your network and computers against attacks and intrusions. A stateful packet firewall carefully inspects incoming traffic packets, looking for known exploits such as malformed, oversized, or out-of-sequence packets. The firewall should be disabled only in special circumstances, such as when you are troubleshooting application issues. This feature is sometimes helpful when you are using some online games and videoconferencing. Be careful when using this feature because it makes the firewall security less effective. See the following section, Configuring Static Routes. If you want the wireless router to respond to a ping from the Internet, select this check box. This should be used only as a diagnostic tool, since it allows your wireless router to be discovered. Do not select this check box unless you have a specific reason to do so. The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 bytes, or 1492 Bytes for PPPoE connections. For some ISPs you might need to reduce the MTU. This is rarely required, and should not be done unless you are sure it is necessary for your ISP connection. See Changing the MTU Size on page 6-6. Customizing Your Network Settings 5-7

72 Table 5-2. WAN Setup Settings Setting NAT Filtering Description Network Address Translation (NAT) determines how the router processes inbound traffic. Secured NAT provides a secured firewall to protect the computers on the LAN from attacks from the Internet, but might prevent some Internet games, point-to-point applications, or multimedia applications from functioning. Open NAT provides a much less secured firewall, but allows almost all Internet applications to function. Setting Up a Default DMZ Server The default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The router is programmed to recognize some of these applications and to work correctly with them, but there are other applications that might not function well. In some cases, one local computer can run the application correctly if that computer s IP address is entered as the default DMZ server. Warning: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network. Incoming traffic from the Internet is usually discarded by the router unless the traffic is a response to one of your local computers or a service that you have configured in the Port Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the default DMZ server. The WAN Setup screen lets you configure a default DMZ server. To assign a computer or server to be a default DMZ server: 1. In the last Default DMZ Server field, type the last digit of the IP address for that computer. To remove the default DMZ server, enter 0 (zero). 2. Select the Default DMZ Server check box, and click Apply. 5-8 Customizing Your Network Settings

73 Configuring Static Routes Static routes provide additional routing information to your router. Under usual circumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network. As an example of when a static route is needed, consider the following case: Your primary Internet access is through a cable modem to an ISP. You have an ISDN router on your home network for connecting to the company where you are employed. This router s address on your LAN is Your company s network address is When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the gateway, and a second static route was created to your local network for all x addresses. With this configuration, if you attempt to access a device on the network, your router forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request is likely to be denied by the company s firewall. In this case you must define a static route, telling your router that should be accessed through the ISDN router at In this example: The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all x.x addresses. The Gateway IP Address field specifies that all traffic for these addresses should be forwarded to the ISDN router at A Metric value of 1 will work since the ISDN router is on the LAN. Private is selected only as a precautionary security measure in case RIP is activated. Customizing Your Network Settings 5-9

74 Select Static Routes under Advanced in the main menu. The Static Routes screen displays. Figure 5-4 To add or edit a static route: 1. Click Add to open the Static Routes screen. Figure In the Route Name field, type a name for this static route. (This is for identification purposes only.) 3. Select the Private check box if you want to limit access to the LAN only. If Private is selected, the static route is not reported in RIP. 4. Select the Active check box to make this route effective. 5. Type the destination IP address of the final destination. 6. Type the IP subnet mask for this destination. If the destination is a single host, type Type the gateway IP address, which must be a router on the same LAN segment as the WNDR3300 router Customizing Your Network Settings

75 8. Type a number between 1 and 15 as the metric value. This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to Click Apply to have the static route entered into the table. Allowing Inbound Connections to Your Network By default, the WNDR3300 router blocks any inbound traffic from the Internet to your computers except for replies to your outbound traffic. However, you might need to create exceptions to this rule for the following purposes: To allow remote computers on the Internet to access a server on your local network. To allow certain applications and games to work correctly when their replies are not recognized by your router. Your router provides two features for creating these exceptions: port forwarding and port triggering. This section explains how a normal outbound connection works, followed by two examples explaining how port forwarding and port triggering operate and how they differ. How Your Computer Accesses a Remote Computer through Your Router When a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing source and destination address and process information. Before forwarding your message to the remote computer, your router must modify the source information and must create and track the communication session so that replies can be routed back to your computer. Here is an example of normal outbound traffic and the resulting inbound responses: 1. You open Internet Explorer, beginning a browser session on your computer. Invisible to you, your operating system assigns a service number (port number) to every communication process running on your computer. In this example, let s say Windows assigns port number 5678 to this browser session. 2. You ask your browser to get a Web page from the Web server at Your computer composes a Web page request message with the following address and port information: The source address is your computer s IP address. The source port number is 5678, the browser session. Customizing Your Network Settings 5-11

76 The destination address is the IP address of which your computer finds by asking a DNS server. The destination port number is 80, the standard port number for a Web server process. Your computer then sends this request message to your router. 3. Your router creates an entry in its internal session table describing this communication session between your computer and the Web server at Before sending the Web page request message to your router stores the original information and then modifies the source information in the request message, performing Network Address Translation (NAT): The source address is replaced with your router s public IP address. This is necessary because your computer uses a private IP address that is not globally unique and cannot be used on the Internet. The source port number is changed to a number chosen by the router, such as This is necessary because two computers could independently be using the same session number. Your router then sends this request message through the Internet to the Web server at 4. The Web server at composes a return message with the requested Web page data. The return message contains the following address and port information: The source address is the IP address of The source port number is 80, the standard port number for a Web server process. The destination address is the public IP address of your router. The destination port number is The Web server then sends this reply message to your router. 5. Upon receiving the incoming message, your router checks its session table to determine whether there is an active session for port number Finding an active session, the router then modifies the message, restoring the original address information replaced by NAT. The message now contains the following address and port information: The source address is the IP address of The source port number is 80, the standard port number for a Web server process. The destination address is your computer s IP address. The destination port number is 5678, the browser session that made the initial request Customizing Your Network Settings

77 Your router then sends this reply message to your computer, which displays the Web page from 6. When you finish your browser session, your router eventually senses a period of inactivity in the communications. Your router then removes the session information from its session table, and incoming traffic is no longer accepted on port number How Port Triggering Changes the Communication Process In the preceding example, requests are sent to a remote computer by your router from a particular service port number, and replies from the remote computer to your router are directed to that port number. If the remote server sends a reply back to a different port number, your router will not recognize it and will discard it. However, some application servers (such as FTP and IRC servers) send replies back to multiple port numbers. Using the port triggering function of your router, you can tell the router to open additional incoming ports when a particular outgoing port originates a session. An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination port The IRC server not only responds to your originating source port, but also sends an identify message to your computer on port 113. Using port triggering, you can tell the router, When you initiate a session with destination port 6667, you must also allow incoming traffic on port 113 to reach the originating computer. Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined: 1. You open an IRC client program, beginning a chat session on your computer. 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your router. 3. Your router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server. 4. Noting your port triggering rule, and having observed the destination port number of 6667, your router creates an additional session entry to send any incoming port 113 traffic to your computer. 5. The IRC server sends a return message to your router using the NAT-assigned source port (as in the previous example, let s say port 33333) as the destination port. The IRC server also sends an identify message to your router with destination port 113. Customizing Your Network Settings 5-13

78 6. Upon receiving the incoming message to destination port 33333, your router checks its session table to determine whether there is an active session for port number Finding an active session, the router restores the original address information replaced by NAT and sends this reply message to your computer. 7. Upon receiving the incoming message to destination port 113, your router checks its session table and learns that there is an active session for port 113, associated with your computer. The router replaces the message s destination IP address with your computer s IP address and forwards the message to your computer. 8. When you finish your chat session, your router eventually senses a period of inactivity in the communications. The router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers or 113. To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application, or user groups or newsgroups. Note: Only one computer at a time can use the triggered application. How Port Forwarding Changes the Communication Process In both of the preceding examples, your computer initiates an application session with a server computer on the Internet. However, you might need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your router ignores any inbound traffic that is not a response to your own outbound traffic. You can configure exceptions to this default rule by using the port forwarding feature. A typical application of port forwarding can be shown by reversing the client-server relationship from our previous Web server example. In this case, a remote computer s browser needs to access a Web server running on a computer in your local network. Using port forwarding, you can tell the router, When you receive incoming traffic on port 80 (the standard port number for a Web server process), forward it to the local computer at The following sequence shows the effects of the port forwarding rule you have defined: 1. The user of a remote computer opens Internet Explorer and requests a Web page from which resolves to the public IP address of your router. The remote computer composes a Web page request message with the following destination information: 5-14 Customizing Your Network Settings

79 The destination address is the IP address of which is the address of your router. The destination port number is 80, the standard port number for a Web server process. The remote computer then sends this request message through the Internet to your router. 2. Your router receives the request message and looks in its rules table for any rules covering the disposition of incoming port 80 traffic. Your port forwarding rule specifies that incoming port 80 traffic should be forwarded to local IP address Therefore, your router modifies the destination information in the request message: The destination address is replaced with Your router then sends this request message to your local network. 3. Your Web server at receives the request and composes a return message with the requested Web page data. Your Web server then sends this reply message to your router. 4. Your router performs Network Address Translation (NAT) on the source IP address, and sends this request message through the Internet to the remote computer, which displays the Web page from To configure port forwarding, you need to know which inbound ports the application needs. You usually can determine this information by contacting the publisher of the application or user groups or newsgroups. How Port Forwarding Differs from Port Triggering The following points summarize the differences between port forwarding and port triggering: Port triggering can be used by any computer on your network, although only one computer can use it at a time. Port forwarding is configured for a single computer on your network. Port triggering does not need to know the computer s IP address in advance. The IP address is captured automatically. Port forwarding requires that you specify the computer s IP address during configuration, and the IP address must never change. Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity. Port forwarding is always active and does not need to be triggered. Customizing Your Network Settings 5-15

80 Configuring Port Forwarding to Local Servers Using the port forwarding feature, you can allow certain types of incoming traffic to reach servers on your local network. For example, you might make a local Web server, FTP server, or game server visible and available to the Internet. Use the Port Forwarding screen to configure the router to forward specific incoming protocols to computers on your local network. In addition to servers for specific applications, you can also specify a default DMZ server to which all other incoming protocols are forwarded. The DMZ server is configured in the WAN Setup screen, as discussed in Setting Up a Default DMZ Server on page 5-8. Before starting, you need to determine which type of service, application, or game you will provide, and the local IP address of the computer that will provide the service. Be sure the computer s IP address never changes. Tip: To ensure that your server computer always has the same IP address, use the reserved IP address feature of your WNDR3300 router. See Address Reservation on page 5-4 for instructions on how to use reserved IP addresses. To configure port forwarding to a local server: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. Figure Customizing Your Network Settings

81 2. From the Service Name list, select the service or game that you will host on your network. If the service does not appear in the list, see the following section, Adding a Custom Service. 3. In the corresponding Server IP Address box, enter the last digit of the IP address of your local computer that will provide this service. 4. Click Add. The service appears in the list in the screen. Adding a Custom Service To define a service, game, or application that does not appear in the Service Name list, you must first determine which port number or range of numbers is used by the application. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups. When you have the port number information, follow these steps: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. 2. Click Add Custom Service. Figure In the Service Name field, enter a descriptive name. 4. In the Service Type field, select the protocol. If you are unsure, select TCP/UDP. 5. In the Starting Port field, enter the beginning port number. If the application uses only a single port, enter the same port number in the Ending Port field. If the application uses a range of ports, enter the ending port number of the range in the Ending Port field. 6. In the Server IP Address field, enter the IP address of your local computer that will provide this service. Customizing Your Network Settings 5-17

82 7. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen. Editing or Deleting a Port Forwarding Entry To edit or delete a port forwarding entry: 1. In the table, select the button next to the service name. 2. Click Edit Service or Delete Service. Application Example: Making a Local Web Server Public If you host a Web server on your local network, you can use port forwarding to allow Web requests from anyone on the Internet to reach your Web server. To make a local Web server public: 1. Assign your Web server either a fixed IP address or a dynamic IP address using DHCP address reservation, as explained in Address Reservation on page 5-4. In this example, your router will always give your Web server an IP address of In the Port Forwarding screen, configure the router to forward the HTTP service to the local address of your Web server at HTTP (port 80) is the standard protocol for Web servers. 3. (Optional) Register a host name with a Dynamic DNS service, and configure your router to use the name as described in Using a Dynamic DNS Service on page 5-5. To access your Web server from the Internet, a remote user must know the IP address that has been assigned by your ISP. However, if you use a Dynamic DNS service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org. Configuring Port Triggering Port triggering is a dynamic extension of port forwarding that is useful in these cases: More than one local computer needs port forwarding for the same application (but not simultaneously). An application needs to open incoming ports that are different from the outgoing port. When port triggering is enabled, the router monitors outbound traffic looking for a specified outbound trigger port. When the router detects outbound traffic on that port, it remembers the IP address of the local computer that sent the data. The router then temporarily opens the specified incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering computer Customizing Your Network Settings

83 While port forwarding creates a static mapping of a port number or range to a single local computer, port triggering can dynamically open ports to any computer that needs them and can close the ports when they are no longer needed. Note: If you use applications such as multiplayer gaming, peer-to-peer connections, realtime communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable Universal Plug and Play (UPnP) according to the instructions in A computer on any wireless or wired LAN segment of the wireless router should be able to connect to the Internet or share files and printers with any other wireless or wired computer or server connected to the other AP. on page To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups. To set up port triggering: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays. 2. Select the Port Triggering radio button. The port triggering information displays. Figure 5-8 Customizing Your Network Settings 5-19

84 3. Clear the Disable Port Triggering check box. Note: If the Disable Port Triggering check box is selected after you configure port triggering, port triggering is disabled. However, any port triggering configuration information you added to the router is retained even though it is not used. 4. In the Port Triggering Timeout field, enter a value up to 9999 minutes. This value controls the inactivity timer for the designated inbound ports. The inbound ports close when the inactivity time expires. This is required because the router cannot be sure when the application has terminated. 5. Click Add Service. Figure In the Service Name field, type a descriptive service name. 7. In the Service User field, select Any (the default) to allow this service to be used by any computer on the Internet. Otherwise, select Single address, and enter the IP address of one computer to restrict the service to a particular computer. 8. Select the service type, either TCP or UDP or both (TCP/UDP). If you are not sure, select TCP/UDP. 9. In the Triggering Port field, enter the number of the outbound traffic port that will cause the inbound ports to be opened. 10. Enter the inbound connection port information in the Connection Type, Starting Port, and Ending Port fields Customizing Your Network Settings

85 11. Click Apply. The service appears in the Port Triggering Portmap table. Wireless Repeating (Also Called WDS) The WNDR3300 router can be used with a wireless access point (AP) to build large bridged wireless networks. Wireless repeating is a type of Wireless Distribution System (WDS). Warning: If you use the wireless repeating function, your options for wireless security are limited to None or WEP. For more information about wireless security, see Chapter 2, Safeguarding Your Network. The following figure shows a wireless repeating scenario: Base Station AP Repeater AP Figure 5-10 To set up a wireless network using WDS, the following conditions must be met for both APs: Both APs must use the same SSID, wireless channel, and encryption mode (see Manually Configuring Your Wireless Settings on page 2-4 or Using Push 'N' Connect (WPS) to Configure Your Wireless Network on page 2-10). Both APs must be on the same LAN IP subnet. That is, all the AP LAN IP addresses are in the same network. Customizing Your Network Settings 5-21

86 All LAN devices (wired and wireless computers) must be configured to operate in the same LAN network address range as the APs. When the wireless router is in dual band mode (the Mode field on the Wireless Settings screen is set to Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz), the WDS function works only in 5GHz 11N mode. To use the 2.4GHz 11g protocol with WDS, set the Mode field in the Wireless Settings screen to Up to 130 Mbps at 2.4 GHz. If you make changes in the Wireless Settings screen, click Apply so that they take effect. Wireless Repeating Function You can view or change wireless repeater settings for the wireless router. From the main menu of the browser interface, under Advanced, click Wireless Repeating Function to display the Wireless Repeating Function screen. Figure 5-11 The wireless router supports two modes of the wireless repeating function, and allows you to control wireless client association: Wireless Repeater. The wireless router sends all traffic from its local wireless or wired computers to a remote AP. To configure this mode, you must know the MAC address of the remote parent AP. Wireless Base Station. The wireless router acts as the parent AP, bridging traffic to and from the child repeater AP, as well as handling wireless and wired local computers. To configure this mode, you must know the MAC addresses of the child repeater AP Customizing Your Network Settings

87 Disable Wireless Client Association. Usually this check box is cleared so that the router is an access point for wireless computers. If this check box is selected, the router communicates wirelessly only with other APs whose MAC addresses are listed in this screen. The router still communicates with wire-connected LAN devices. Setting Up the Base Station The wireless repeating function works only in hub and spoke mode. The units cannot be daisy chained. You must know the wireless settings for both units. You must know the MAC address of the remote unit. First, set up the base station, and then set up the repeater. To set up the base station: 1. Set up both units with exactly the same wireless settings (SSID, mode, channel, and security). Note that the wireless security option must be set to None or WEP. 2. Log into the wireless router base unit, under the Advanced heading, select Wireless Repeating Function to display the Wireless Repeating Function screen. Figure Select the Enable Wireless Repeating Function check box and the Wireless Base Station radio button. 4. Enter the MAC address for the repeater units. 5. Click Apply to save your changes. Customizing Your Network Settings 5-23

88 Setting Up a Repeater Unit Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the wireless connection to the base station. Note: If you are using the WNDR3300 base station with a non-netgear wireless router as the repeater, you might need to change additional configuration settings. In particular, you should disable the DHCP server function on the wireless repeater AP. To configure a WNDR3300 router as a repeater unit: 1. If you are using the same model of wireless router for both the base station and repeaters, you must change the LAN IP address for each repeater to a different IP address in the same subnet (see Using the LAN Setup Options on page 5-1). Note: Failing to change the LAN IP address will cause an IP address conflict in the network because the factory default LAN IP is the same for both units. 2. Log in to the router that will be the repeater. Check the Wireless Settings screen, and verify that the wireless settings match the base unit exactly. The wireless security option must be set to WEP or None. 3. In the Wireless Repeating Function screen, select the Enable Wireless Repeater Mode radio button. This IP address must be in the same subnet as the base station but different from the LAN IP of the base station. 4. Fill in the Base Station MAC Address field. 5. Click Apply to save your changes. 6. Verify connectivity across the LANs. A computer on any wireless or wired LAN segment of the wireless router should be able to connect to the Internet or share files and printers with any other wireless or wired computer or server connected to the other AP Customizing Your Network Settings

89 Chapter 6 Fine-Tuning Your Network This chapter describes features to help you manage your RangeMax Dual Band Wireless-N Router WNDR3300. This chapter includes the following sections: Assessing Your Speed Requirements on page 6-2 Optimizing Your Network Bandwidth on page 6-3 Optimizing Wireless Performance on page 6-5 Changing the MTU Size on page 6-6 Quality of Service (QoS) on page 6-7 Common connection types and their speed and security considerations are: Broadband Internet. Your Internet connection speed is determined by your modem type, such as ADSL or cable modem, as well as the connection speed of the sites to which you connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when you connect to another site that also has an asymmetrical connection, the data rate between your sites is limited by each side s upstream data rate. A typical residential ADSL or cable modem connection provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps. Wireless. Your RangeMax Dual Band Wireless-N Router WNDR3300 provides a wireless data throughput of up to 300 Mbps using technology called multiple input, multiple output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With the introduction of the newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong. To get the best performance, use RangeMax NEXT adapters such as the WN511B for your computers. Although the RangeMax NEXT router is compatible with older b and g adapters, the use of these older wireless technologies in your network can result in lower throughput overall (typically less than 10 Mbps for b and less than 40 Mbps for g). In addition, many older wireless products do not support the latest security protocols, WPA and WPA2. Fine-Tuning Your Network 6-1

90 Powerline. For connecting rooms or floors that are blocked by obstructions or are distant vertically, consider networking over your building s AC wiring. NETGEAR s Powerline HD family of products delivers up to 200 Mbps to any outlet, while the older-generation XE family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting. The Powerline HD family of products can coexist on the same network with older-generation XE family products or HomePlug 1.0 products, but they are not interoperable with these older products. Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on newer computers, wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A wired connection is not susceptible to interference, and eavesdropping would require a physical connection to your network. Note: Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate. Assessing Your Speed Requirements Because your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies might not improve your Internet experience. However, many emerging home applications require high data rates. For example: Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need. Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems. 6-2 Fine-Tuning Your Network

91 Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 6-1 shows the time to transfer 1 gigabyte (GB) of data using various networking technologies. Table 6-1. Theoretical Transfer Time for 1 Gigabyte Network Connection Gigabit wired Ethernet RangeMax NEXT Wireless-N Powerline HD Theoretical Raw Transfer Time 8 seconds 26 seconds 40 seconds 100 Mbps wired Ethernet 80 seconds n wireless 45 seconds g wireless 150 seconds b wireless 700 seconds 10 Mbps wired Ethernet 800 seconds Cable modem (3 Mbps) Analog modem (56 kbps) 2700 seconds 144,000 seconds (40 hours) Optimizing Your Network Bandwidth As your network grows, it might consist of several segments of different networking technologies, each providing different throughput. In planning your network, you should first consider which devices will have the heaviest traffic flow between them. Examples are: A media center in one room streaming high-definition video from a server in another room A storage device that is used for backing up your computers Fine-Tuning Your Network 6-3

92 Next, consider the throughput of your network devices. Where possible, make the heaviest-traffic connections using higher-speed technologies, with no lower-speed bottlenecks in the path. RangeMax Dual Band Wireless-N Router WNDR3300 Figure 6-1 Figure 6-1 shows a sample network using multiple networking technologies. In this network, the two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the GS605 switch to the storage server. This connection should allow for extremely fast backups or quick access to large files on the server. The PC connected through a pair of Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this example would be sufficient for high-traffic applications such as streaming HD video, the use of older devices such as 10 Mbps Ethernet or b wireless would create a significant bottleneck. 6-4 Fine-Tuning Your Network

93 Optimizing Wireless Performance The speed and operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless router. You should choose a location for your router that will maximize the network speed. Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range and performance specifications, click the link to the online document Wireless Networking Basics in Appendix B. The following list describes how to optimize wireless router performance. Identify critical wireless links. If your network has several wireless devices, decide which wireless devices need the highest data rate, and locate the router near them. Many wireless products have automatic data-rate fallback, which allows increased distances without loss of connectivity. This also means that devices that are farther away might be slower. Therefore, the most critical links in your network are those where the traffic is high and the distances are great. Optimize those first. Choose placement carefully. For best results, place your router: Near the center of the area in which your computers will operate. In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls). Avoid obstacles to wireless signals. Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets, refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions. Keep away from large amounts of water such as fish tanks and water coolers. Reduce interference. Avoid windows unless communicating between buildings. Place wireless devices away from various electromagnetic noise sources, especially those in the MHz frequency band. Common noise-creating sources are: Computers and fax machines (no closer than 1 foot) Copying machines, elevators, and cell phones (no closer than 6 feet) Fine-Tuning Your Network 6-5

94 Microwave ovens (no closer than 10 feet) Choose your settings. Use a scanning utility to determine what other wireless networks are operating nearby, and choose an unused channel. Turn off SSID broadcast, and change the default SSID. Other nearby devices might automatically try to connect to your network several times a second, which can cause significant performance reduction. Use WMM to improve the performance of voice and video traffic over the wireless link. Changing the MTU Size The Maximum Transmission Unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If any device in the data path has a lower MTU setting than the other devices, the data packets must be split or fragmented to accommodate the one with the smallest MTU. The best MTU setting for NETGEAR equipment is often just the default value, and changing the value might fix one problem but cause another. Leave MTU unchanged unless one of these situations occurs: You have problems connecting to your ISP or other Internet service, and the technical support of either the ISP or NETGEAR recommends changing the MTU setting. These might require an MTU change: A secure website that won t open, or displays only part of a Web page Yahoo MSN America Online s DSL service You use VPN and have severe performance problems. You used a program to optimize MTU for performance reasons, and now you have connectivity or performance problems. Note: An incorrect MTU setting can cause Internet communication problems such as the inability to access certain Web sites, frames within Web sites, secure login pages, or FTP or POP servers. 6-6 Fine-Tuning Your Network

95 If you suspect an MTU problem, a common solution is to change the MTU to If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. Table 6-2 describes common MTU sizes and applications. Table 6-2. Common MTU Sizes MTU Application 1500 The largest Ethernet packet size and the default value. This is the typical setting for non- PPPoE, non-vpn connections, and is the default value for NETGEAR routers, adapters, and switches Used in PPPoE environments Maximum size to use for pinging. (Larger packets are fragmented.) 1468 Used in some DHCP environments Usable by AOL if you don't have large attachments, for example Used in PPTP environments or with VPN Maximum size for AOL DSL. 576 Typical value to connect to dial-up ISPs. To change the MTU size: 1. In the main menu, under Advanced, select WAN Setup. 2. In the MTU Size field, enter a new size between 64 and Click Apply to save the new configuration. Quality of Service (QoS) QoS is an advanced feature that can be used to prioritize some types of traffic ahead of others. The WNDR3300 router can provide QoS prioritization over the wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen. Fine-Tuning Your Network 6-7

96 From the main menu, under Advanced, select QoS Setup. The QoS Setup screen displays: Figure 6-2 Using WMM QoS for Wireless Multimedia Applications The WNDR3300 router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application must be WMM enabled. Legacy applications that do not support WMM, and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video. WMM QoS is enabled by default. You can disable it in the QoS Setup screen, shown in Figure 6-2 on page 6-8, by clearing the Enable WMM check box and clicking Apply. 6-8 Fine-Tuning Your Network

97 Configuring QoS for Internet Access You can give prioritized Internet access to the following types of traffic: For specific applications For specific online games On individual Ethernet LAN ports of the router From a specific device by MAC address To specify prioritization of traffic, you must create a policy for the type of traffic and add the policy to the QoS Policy table in the QoS Setup screen. For convenience, the QoS Policy table lists many common applications and online games that can benefit from QoS handling.

Universal Plug and Play Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. Note: If you use applications such as multiplayer gaming, peer-to-peer connections, realtime communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP. To turn on Universal Plug and Play: 1. From the main menu, under Advanced, click UPnP. The UPnP screen displays. Figure The available settings and information in this screen are: Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If this check box is not selected, the router does not allow any device to automatically control the resources, such as port forwarding (mapping) of the router. Advertisement Period. The advertisement period is how often the router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations might compromise the freshness of the device status but can significantly reduce network traffic. Fine-Tuning Your Network 6-13

102 Advertisement Time To Live. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it might be necessary to increase this value. UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address. 3. Click Apply to save your settings Fine-Tuning Your Network

Plug in the modem and turn it on. Wait 2 minutes. 4. Turn on the wireless router and wait 1 minute. 5. Turn on the computers. Troubleshooting 7-1

104 Table 7-1. Quick Tips (continued) Recommendation Instructions Make sure that the Ethernet cables are securely plugged in. Make sure that the wireless settings in the computer and router match exactly. Make sure that the network settings of the computer are correct. The Internet status light on the wireless router is on if the Ethernet cable connecting the wireless router and the modem is plugged in securely and the modem and wireless router are turned on. For each powered-on computer connected to the wireless router by an Ethernet cable, the corresponding numbered router LAN port light is on. For a wirelessly connected computer, the wireless network name (SSID) and wireless security settings of the router and wireless computer must match exactly. If you set up an Access List in the Advanced Wireless Settings screen, you must add each wireless computer s MAC address to the router s access list. Wired and wirelessly connected computers must have network (IP) addresses on the same network as the router. The simplest way to do this is to configure each computer to obtain an IP address automatically using DHCP. Click the link to the online document Preparing Your Network in Appendix B, or see the documentation that came with your computer. Some cable modem service providers require you to use the MAC address of the computer initially registered on the account. You can view the MAC address in the Attached Devices screen. Check the Test light to verify correct router operation. If the Test light does not turn off within 2 minutes after you turn the router on, reset the router according to the instructions in Restoring the Default Configuration and Password on page Troubleshooting

105 Troubleshooting Basic Functions After you turn on power to the router, the following sequence of events should occur: 1. When power is first applied, verify that the Power light is on. 2. After approximately 10 seconds, verify that: The Power light is solidly on. The Internet light is on. A numbered Ethernet port light is on for any local port that is connected to a computer. This indicates that a link has been established to the connected device. If any of the above conditions does not occur, see the following table. Table 7-2. Troubleshooting Basic Functions Situation Power light is off or is blinking. Lights never turn off. Recommended Action Make sure that the power cord is properly connected to your router and that the power adapter is properly connected to a functioning power outlet. Check that you are using the 12V DC 1A power adapter that NETGEAR supplied for this product. If the Power light alternately blinks green and amber every second, the router software is corrupted. This can happen if a firmware upgrade is interrupted, or if the router detects a problem with the firmware. If the error persists, you have a hardware problem. For recovery instructions, or help with a hardware problem, contact Technical Support at When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the lights stay on, there is a fault within the router. If all lights are still on 1 minute after power up: Cycle the power to see if the router recovers. Clear the router s configuration to factory defaults as explained in Restoring the Default Configuration and Password on page If the error persists, you might have a hardware problem and should contact Technical Support at Troubleshooting 7-3

106 Table 7-2. Troubleshooting Basic Functions Situation The Internet or Ethernet port lights are off. Wireless light is off. Recommended Action If either the Ethernet port lights or the Internet light does not light when the Ethernet connection is made, check the following: Make sure that the Ethernet cable connections are secure at the router and at the modem or computer. Make sure that power is turned on to the connected modem or computer. Be sure that you are using the correct cable: When connecting the router s Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable. If the Wireless light does not come on, verify that the Enable Wireless Router Radio check box is selected in the Advanced Wireless Settings screen. See Advanced Wireless Settings on page Cannot Access the Router Main Menu If you are unable to access the router s main menu from a computer on your local network, check the following: If you are connecting from a wireless computer, try connecting from a wired computer. Check the Ethernet connection between the wired computer and the router. Make sure that the cable connections are secure, and that you are using the correct cable. Make sure that your computer s IP address is on the same subnet as the router. For instructions, click the link to the online document Preparing Your Network in Appendix B to configure your computer. Note: If your computer s IP address is shown as x.x: Windows and Mac OS generate and assign an IP address if the computer cannot reach a DHCP server. These autogenerated addresses are in subnet x.x. If your IP address is in this range, check the connection from the computer to the router, and reboot your computer. Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure that the Java applet is loaded. Try closing the browser and opening it again, or try a different browser. 7-4 Troubleshooting

If the router does not save configuration changes that you have made, check the following: When entering configuration settings, be sure to click Apply before moving to another screen or tab, or your changes could be lost. Click Refresh or Reload in the Web browser. The changes might have occurred, but the Web browser might be caching the old configuration. Cannot Access the Internet If you can access your router but you are unable to access the Internet, first determine whether the router can obtain an IP address from your Internet Service Provider (ISP). Unless your ISP provides a fixed IP address, your router must request an IP address from the ISP. You can determine whether the request was successful using the Router Status screen. To check the WAN IP address: 1. Start your browser, and select an external site such as 2. Access the main menu of the router s configuration at 3. Under Maintenance, select Router Status. 4. Check that an IP address is shown for the Internet port. If is shown, your router has not obtained an IP address from your ISP. If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL modem to recognize your new router by restarting your network, as described in Table 7-1 on page 7-1. If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following: Your ISP might require a login program. Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login. If your ISP requires a login, the login name and password might be set incorrectly. Your ISP might check for your computer s host name. Assign the computer host name of your ISP account as the account name in the Basic Settings screen. Troubleshooting 7-5

108 Your ISP allows only one Ethernet MAC address to connect to Internet and might check for your computer s MAC address. In this case, do one of the following: Inform your ISP that you have bought a new network device, and ask them to use the router s MAC address. Configure your router to spoof your computer s MAC address. If your router can obtain an IP address, but your computer is unable to load any Web pages from the Internet: Your computer might not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the router s configuration, reboot your computer, and verify the DNS address as described in the online document you can access from Preparing Your Network in Appendix B. You can also configure your computer manually with DNS addresses, as explained in your operating system documentation. Your computer might not have the router configured as its TCP/IP gateway. If your computer obtains its information from the router by DHCP, reboot the computer, and verify the gateway address as described in the online document you can access from Preparing Your Network in Appendix B. You might be running login software that is no longer needed. If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that software after installing your router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection. Troubleshooting a Network Using the Ping Utility Most network devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. You can easily troubleshoot a network by using the ping utility in your computer or workstation. Testing the LAN Path to Your Router You can ping the router from your computer to verify that the LAN path to your router is set up correctly. 7-6 Troubleshooting

109 To ping the router from a running Windows PC: 1. From the Windows toolbar, click the Start button, and then select Run. 2. In the field provided, type ping followed by the IP address of the router, as in this example: ping 3. Click OK. You should see a message like this one: Pinging <IP address > with 32 bytes of data If the path is working, you see this message: Reply from < IP address >: bytes=32 time=nn ms TTL=xxx If the path is not working, you see this message: Request timed out If the path is not functioning correctly, you could have one of the following problems: Wrong physical connections For a wired connection, make sure the numbered Ethernet port light is on for the port to which you are connected. If the light is off, follow the instructions in Table 7-2 on page 7-3. Check that the corresponding Link lights are on for your network interface card. If your router and computer are connected to a separate Ethernet switch, make sure the Link lights are on for the switch ports that are connected to your computer and router. Wrong network configuration Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer. Verify that the IP address for your router and your computer are correct and that the addresses are on the same subnet. Testing the Path from Your Computer to a Remote Device After verifying that the LAN path works correctly, test the path from your computer to a remote device. 1. From the Windows toolbar, click the Start button, and then select Run. 2. In the Windows Run window, type: ping -n 10 <IP address> where <IP address> is the IP address of a remote device such as your ISP s DNS server. Troubleshooting 7-7

110 If the path is functioning correctly, replies like those shown in the previous section are displayed. If you do not receive replies: Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information is not visible in your computer s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in the online document you can access from Preparing Your Network in Appendix B. Check to see that the network address of your computer (the portion of the IP address specified by the subnet mask) is different from the network address of the remote device. Check that your cable or DSL modem is connected and functioning. If your ISP assigned a host name to your computer, enter that host name as the account name in the Basic Settings screen. Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, you must configure your router to clone or spoof the MAC address from the authorized computer. Problems with Date and Time Under Content Filtering in the main menu, select to display a screen that shows the current date and time of day. The WNDR3300 router uses the Network Time Protocol (NTP) to obtain the current time from one of several network time servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include the following: Date shown is January 1, Cause: The router has not yet successfully reached a Network Time Server. Check that your Internet access is configured correctly. If you have just completed configuring the router, wait at least 5 minutes, and check the date and time again. Time is off by one hour. Cause: The router does not adjust for daylight savings time. In the screen, select the Adjust for Daylight Savings Time check box. 7-8 Troubleshooting

111 Wireless Connectivity The first steps in solving wireless connection problems are these: 1. Using your wireless card s setup utility program, make sure that your wireless card can find your wireless router. 2. Configure and test with the simplest wireless connection possible, and then add security. The topics in this section describe these steps. Using Your Wireless Card Setup Program When you install a NETGEAR wireless card in your computer, a Smart Wizard utility program is installed that can provide helpful information about your wireless network. You can find this program in your Windows Program menu or as an icon in your system tray. Other wireless card manufacturers might include a similar program. If you have no specific wireless card setup program installed, you can use the basic setup utility in Windows by following these steps: 1. Open the Windows Control Panel, and double-click Network Connections. 2. In the LAN section, double-click Wireless Network Connection. Use the setup program to scan for available wireless networks. Look for a network name (SSID) of NETGEAR or your custom SSID if you have changed it. If your wireless network does not appear, check these conditions: Is your router s wireless radio enabled? See Advanced Wireless Settings on page Is your router s SSID broadcast enabled? See. Advanced Wireless Settings on page 2-15 Is your router set to a wireless standard that is not supported by your wireless card? Check the Mode setting, as described in Manually Configuring Your Wireless Settings on page 2-4. If your wireless network appears, but the signal strength is weak, check these conditions: Is your router too far from your computer, or too close? Place your computer near the router, but at least 6 feet away, and see whether the signal strength improves. Is your wireless signal obstructed by objects between the router and your computer? See Wireless Placement and Range Guidelines on page 2-2. If your wireless network appears and has good signal strength, configure your wireless card and router for the simplest possible connection, as described in the next section. Troubleshooting 7-9

112 Setting Up and Testing Basic Wireless Connectivity Note: If you use a wireless computer to change wireless settings, you might be disconnected when you click Apply. Reconfigure your wireless adapter to match the new settings, or access the wireless router from a wired computer to make any further changes. Follow these instructions to set up and test basic wireless connectivity. Once you have established basic wireless connectivity, you can enable security settings appropriate to your needs. 1. Select Wireless Settings under Setup in the main menu of the WNDR3300 router. Figure For the wireless network name (SSID), use the default name, or choose a suitable descriptive name. In the Name (SSID) field, you can enter a value of up to 32 alphanumeric characters. The default SSID is NETGEAR. Note: The SSID is case-sensitive; NETGEAR is not the same as netgear. Also, the SSID of any wireless access adapters must match the SSID you configure in the RangeMax Dual Band Wireless-N Router WNDR3300. If they do not match, you will not get a wireless connection to the WNDR3300 router. 3. Select the region in which the wireless interface will operate. 4. Set the channel. The default channel is Auto Troubleshooting

113 This field determines which operating frequency is used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point. Select a channel that is not being used by any other wireless networks within several hundred feet of your router. For more information about the wireless channel frequencies, click the link to the online document Wireless Networking Basics in Appendix B. 5. Set the mode to Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz. 6. For Security Options, select None. 7. Click Apply to save your changes. Note: If you are configuring the router from a wireless computer and you change the router s SSID, channel, or security settings, you will lose your wireless connection when you click Apply. You must then change the wireless settings of your computer to match the router s new settings. 8. Select Wireless Settings under Advanced in the main menu of the WNDR3300 router. Figure Make sure the Enable Wireless Router Radio and Enable SSID Broadcast check boxes are selected. 10. Click Setup Access List. 11. Make sure that the Turn Access Control On check box is not selected. 12. Configure and test your wireless computer for wireless connectivity. Troubleshooting 7-11

114 Program the wireless adapter of your computer to have the same SSID and channel that you configured in the router, and disable encryption. Check that your computer has a wireless link and can obtain an IP address by DHCP from the router. Once your computer has basic wireless connectivity to the router, you can configure the advanced wireless security functions of the computer and router (for more information about security, see Chapter 2, Safeguarding Your Network ). Restoring the Default Configuration and Password This section explains how to restore the factory default configuration settings, changing the router s administration password back to password. You can erase the current configuration and restore factory defaults in two ways: Use the Erase function of the router (see Erasing the Configuration on page 4-10). Use the Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known. To restore the factory default configuration settings when you do not know the administration password or IP address, you must use the restore settings button on the rear panel of the router. 1. Press and hold the restore settings button for 10 seconds. 2. Release the restore settings button, and wait for the router to reboot. If the wireless router fails to restart, or the Power light continues to blink or turns solid amber, the unit might be defective. If the error persists, you might have a hardware problem and should contact Technical Support at Troubleshooting
